For the fifth episode of H∆SHTAG$ — our web series chronicling Internet-based music — we explore the world of Tumblrwave. The microblogging site Tumblr has given a voice to a wide variety of artists in its short history: queer rapper Le1f, R&B new hope Kilo Kish and seapunk founders Zombelle and Ultrademon. What’s fascinating is that, musically, there’s not a ton that connects them. It’s Tumblr: A site that offers them one of the best ways to express themselves.
